Inorganic no carbon
Acids release hydrogen ions when dissolved in water(0-6 on the pH scale)
Bases release hydroxide ions when dissolved in water(8-14 on the pH scale)
pH Scale a way to measure how acidic or basic a chemical is
Organic contains carbon as the major component
Carbohydrates sugars! immediate energy source
Monosaccharides simple sugars
Disaccharides double sugars formed by 2 monosaccharides joining together by dehydration synthesis. (protein key)
Polysaccharides polymers (long branching chains of linked monosaccharides) linked together by dehydration synthesis. (large & fairly insoluble which make them ideal storage products)
Hydrophilic likes water
Hydrophobic dislike waters
Neutral Fats - Triglycerides long term energy storage no oxygen does not dissolve in water
Phospholipids cell membrane structure dissolves in water
Steroids Hormones made my cholesterol
Proteins structure, enzymes, regulation
Amino Acids building blocks of proteins (2 types: fibrous and globular)
Peptide Bond primary structure of proteins
Isotonic Solutions same solution
Hypotonic Solutions more water
Hypertonic Solutions less water
Mitosis cell division
Cell Physiology DNA makes RNA RNA makes Protein
DNA Deoxyribose Nucleic Acid (hereditary material)
RNA Ribose Nucleic Acid (controls protein structure)
ATP Adenosine Tri Phosphate (energy molecule)
Diffusion the spreading of particles from an area of higher concentration to an area of lower concentration
